Forest Landscape Dynamics: a Semi-Markov Modeling Approach

Description: A transition model (MOSAIC) is used to describe forest dynamics at the landscape scale. The model uses a semi-Markov framework by considering transition probabilities and Erlang distributed holding times in each transition. Parameters for the transition model are derived from a gap model (ZELIG). This procedure ensures conceptual consistency of the landscape model with the fine scale ecological detail represented by the forest gap model. Spatial heterogeneity in the transition model is driven b… more

A Structural Equation Analysis of Intergenerational Differences in Attitudes toward Individual Modernity in the United Arab Emirates: Implications for Cross-Cultural Research

Description: It has been widely believed that modernity is a byproduct of a nuclear family system, a highly urbanized society, and a secular way of life. As such, developing countries are characterized as modern insofar as their social and cultural structures are able to correspond to these criteria. To examine the validity of these propositions, data on two randomly-selected generations--daughters and mothers in the United Arab Emirates--were generated.

Performance of Children With and Without Traumatic Brain Injury on the Process Scoring System for the Intermediate Category Test

Description: The clinical utility of the Intermediate Category Test, a measure of executive functioning in children 9 to 14 years of age, is currently limited by the availability of only a Total Error score for normative interpretation. The Process Scoring System (PSS) was developed to provide a standardized method of assessing specific processing patterns and problem-solving errors. The purpose of this study was to determine the ability of the PSS scores to discriminate between children with and without su… more

Self-Efficacy and Selected Variables as Predictors of Persistence for First Quarter Students at a Proprietary Institution

Description: Proprietary colleges are uniquely different from two or four year colleges due to the emphasis on the student establishing a definite career path prior to enrollment. Because of this career track emphasis, Bandura's (1977) postulation that self-efficacy is a significant variable influencing task completion may offer insight into the challenge of student retention at a proprietary college. The study's purpose was to determine if career self-efficacy, demographic factors, and academic preparednes… more

The Fractal Stochastic Point Process Model of Molecular Evolution and the Multiplicative Evolution Statistical Hypothesis

Description: A fractal stochastic point process (FSPP) is used to model molecular evolution in agreement with the relationship between the variance and mean numbers of synonymous and nonsynonymous substitutions in mammals. Like other episodic models such as the doubly stochastic Poisson process, this model accounts for the large variances observed in amino acid substitution rates, but unlike other models, it also accounts for the results of Ohta's (1995) analysis of synonymous and nonsynonymous substitution… more
